Remove extraneous newline trims for inet_http_server section

If you configure the default recipe with the attributes:

```ruby
:supervisor => {
	:inet_port => "127.0.0.1:9001",
	:inet_username => "analysis",
	:inet_password => "analysis"
},
```

you will get a output in the /etc/supervisord.conf like this

```
...
[inet_http_server]
port=127.0.0.1:9001username=analysispassword=analysis
[supervisord]
...
```

With this configuration line in conf file the supervisord daemon fails to start like this

```
---- Begin output of /etc/init.d/supervisor start ----
STDOUT: Starting supervisor:
STDERR: /usr/local/lib/python2.7/dist-packages/supervisor/options.py:295: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security.
  'Supervisord is running as root and it is searching '
Error: not a valid port number: '9001username=analysispassword=analysis'
```

Solution: Remove the newline tims.
